1.1 INSTALLATION
RECOMMENDATIONS.
The place of installation of the appliance and
relative Immergas accessories must have suitable
features (technical and structural) such to allow
(always in safety, efficiency and comfortable
conditions):
- installation (according to the provisions of the
technical legislation and technical regulations);
- maintenance operations (including scheduled,
periodic, routine and special maintenance);
- removal (to outdoors in the place for loading
and transporting the appliances and compo-
nents) as well as their eventual replacement
with appliances and/or equivalent components.
Only professionally enabled companies are au-
thorised to install Immergas appliances.
Installation must be carried out according to
regulation standards, current legislation and in
compliance with local technical regulations and
the required technical procedures.
Before installing the appliance, ensure that it is
delivered in perfect condition; if in doubt, contact
the supplier immediately. Packing materials (sta-
ples, nails, plastic bags, polystyrene foam, etc.)
constitute a hazard and must be kept out of the
reach of children.
If the appliance is installed inside or between
cabinets, ensure sufficient space for normal
servicing; therefore it is advisable to leave a gap
of 2÷3 cm between the storage tank casing and
the sides of the cabinet.
In the event of malfunctions, faults or incorrect
operation, turn the appliance off and contact an
authorised company (e.g. the Authorised Tech-
nical Assistance centre, which has specifically
trained staff and original spare parts). Do not
attempt to modify or repair the appliance alone.
Failure to comply with the above implies personal
responsibility and invalidates the warranty.
• Installation standards: these storage tanks
have been designed for floor installation; they
must be used for the storage of domestic hot
water and similar purposes. They have not be
designed for wall-installation.
Attention:
these units are used to store water at a
temperature below boiling point at atmospheric
pressure. They must be connected to a boiler
and to a DHW water distribution network. They
must be installed in rooms where the temperature
cannot fall below 0°C and must not be exposed
to atmospheric agents.
"Anti-legionella" heat treatment of the Immergas
storage tank (activated by the specific function
present on the predisposed thermoregulatory
systems): during this stage, the temperature of
the water inside the storage tank exceeds 60°C
with a relative risk of burns. Keep this domestic
water treatment under control (and inform
the users) to prevent unforeseeable damage
to people, animals, things. If required install a
thermostatic valve on the domestic hot water
outlet to prevent scalding.
